Description

Message exchange and method that distributed network computing system and this system use

Technical field

The present invention relates to connect the distributed network computing system of a plurality of terminal equipments, particularly relate to public network, cable LAN (wired Local Area Network, call wired lan in the following text), WLAN (wireless local area network) (wireless Local Area Network, call WLAN in the following text) etc. multiple communication network and depositing, to being connected in the portable data assistance on these communication networks, personal computer (PC), the various terminal equipments that disposal abilities such as portable PC are different provide the distributed network computing system of applied business of application software such as stock control and message exchange and information switching method and the medium that this system uses.

Background technology

Existing computed information processing, its main flow are to connect the centralized processing system that a plurality of terminals are used on a master computer.In contrast, with network a plurality of computers are coupled together, share all resources of each computer, the system that can handle expeditiously is a distributed processing system (DPS), is used between different machines being called distributed computing environment (DCE) to using the environment that software carries out distribution process.

Realize in the network environment of Distributed Calculation the user needn't know where are program and data.Because logically whole network similarly is that a computer operates like that, the user can utilize necessary information and function from the operating environment of oneself.

Yet, in network environment as described above, for example consider that applied business with various application software such as inventory management business offers under the situation of system of each terminal equipment, the disposal ability of the employed terminal equipment of user (is referred to as terminal attribute, the ability that comprises CPU, and display frame size and memory span etc.) height is respectively arranged, in order to absorb the height difference of this disposal ability, need use artificial information operating in terminal one side or server one side.

Also have, each terminal equipment for example is connected in public network or is connected in wired and wireless LAN etc., and the communication network of utilization has nothing in common with each other.Thereby each communication network also exists relative different as communications infrastructure message transmission rate, transmission quantity, quality etc.

Usually, if be high level with the disposal ability as the personal computer of universal machine, then portable data assistance is medium, and other-end in addition is inferior level.Again, as the communications infrastructure, the transmission quantity of wired or wireless LAN and quality all are first-class levels, and ISDN (integrated services digitalnetwork, be integrated service digital network) for medium level, simulating wired, analog or digital radio communication is inferior level.

In network environment, there is above-mentioned difference in the disposal ability of each terminal equipment, also has the difference of the communication capacity of the communications infrastructure.Thereby it is very difficult providing the common application business to each terminal equipment under such environment.

And its attribute of the terminal equipment that uses in system has determined when system design, normally provides applied business according to its attribute.Therefore, even also exist developmental research to go out to have the terminal equipment of new attribute, also be not easy the problem of using in the import system.

Again, the difficulty that causes for the difference of the difference that overcomes the above-mentioned disposal ability of each terminal equipment and communications infrastructure communication capacity provides professional, need complicated processing, therefore exist to need to use to have the problem of handling the large server computer of corresponding ability with this.

In enterprises such as company, factory, need be provided for house phone each other and the switch that is connected with the exchange of user telephone line (outside line) of house phone again.Usually intramural switch or intramural switching equipment are called PBX (private branch exchange, i.e. private branch exchange), particularly digital inner exchanging machine is called digital pbx.Digital pbx is handled owing to voice signal is transformed to digital signal, therefore OA machines such as the personal computer that uses in the unit, word processor, computer is connected in digital pbx, can carry out comprehensive and effectively processing to these data and sound.By means of additional various types of network functions on digital pbx, can construct wider network again by the communication network of office inside.

When constructing LAN for the first time, in most cases be to go up linking number platform computer machine at an Ethernet (Ethernet) cable (coaxial cable) again.But in case networking further develops, the machine of connection increases, and just is subjected to the restriction of the cable physical length limit.As surmount this restriction physically and the instrument of all network being expanded in logic router etc. is arranged.

Router can constitute closed network, and selected only route (selection route), and necessary packets of information is passed through.Router after then adjudicating according to node serial number, is determined final arrival place location earlier according to the judgement of the network numbering in the Internet protocol (network layer).

Internet protocol in network layer is because of agreement define method differences such as TCP/IP, OSI, so router is supported a kind of agreement basically.In other words, can select the network of specific protocol from various protocols and the backbone network of depositing, from the Ethernet to the circuit, be effective in the underspeed place of load factor of decision of needs.

But, never proposed to compensate the difference of each such as mentioned above terminal equipment disposal ability and the communication capacity difference of the communications infrastructure such as on the such network connection device of above-mentioned switch and router, professional system is provided.

On the other hand, need managing large scale, and might be distributed data structure.For this reason, among the WWW (World Wide Web) that extensively popularizes on the internet, use the structured language (SGML) that is called HTML (hyper textmarkup language) at present.And to the structured language beyond the HTML, expectation is along with CALS's (Continuos Acquisition and Lifecycle Support) popularizes, and SGML (Standard Generalized Markup Language) can popularize from now on.

In order to show the file of making of these structured languages, end side needs the analytic structure language, make its demonstration browser function.In other words, to not having the terminal equipment of browser function, can not provide the information of describing with structured language.

And if intactly the information of bar structure language record sends to network, then might make a large amount of information also flow to the low circuit of transmittability, thereby spend more time taking problem.Particularly this has become deep problem under the line quality condition of poor.Also have, such problem also is identical for for example OLE cell data forms such as (object linking and embedding) beyond HTML.

Fig. 6 is the block diagram of the internal structure of expression communications infrastructure Information Management Department 15.These represent the attribute information of the communication capacity of each communication network communications infrastructure Information Management Department 15 management data transmission rates, transmission quantity, quality.This communications infrastructure Information Management Department 15 is made of message exchange intercommunication interface portion 151, communications infrastructure Features Management portion 152 and retransmission process/circuit blocking-up punishment management department 153.

Message exchange intercommunication interface portion 151 be used for message exchange 10 in the interface that communicates of other key elements.Communications infrastructure Features Management portion 152 manages as label informations such as the transmission quality of communications facility and transmission rates.The function of the processing when retransmission process/circuit blocking-up punishment management department 153 is furnished with the communications infrastructure that uses according to the user and carries out retransmission process and circuit blocking-up.

Action to this example is illustrated below.

At first handling operation with regard to the conventional applied business under the situation of not using message exchange 10, is that example describes with the inventory management business.

Fig. 7 is the flow chart of the processing operation of the conventional applied business of expression.Server computer 1 is accepted input from image reader 43 by wired lan 40, sends information such as stock's bill to applied business portion 22 (steps A 11).At server computer 1, applied business portion 20 extracts from the billing information that image reader 43 reads thinks the quantity in stock that needs, and this content output is shown in the display frame of PC41 (steps A 12) using the user of PC41 for example.

Utilize this demonstration, the user is with being connected in PC41 on the server computer 1, carries out quantity in stock is updated to the information processing (steps A 13) of up-to-date information etc.Reception outputs to printer 42 (steps A 14) to new stock's bill of this result of reaction from the applied business portion 20 of user's update information.By means of this, the user can obtain new stock's bill from the output result of printer 42.

General applied business like this can use PC41, printer 42, image reader 43 to be prerequisite with the user at one's side.In the example of Fig. 1, PC41, printer 42, image reader 43 are connected with server computer 1 by wired lan 40 in office.

The following describes the situation that the user at office outdoor application portable data assistance 31 and portable PC 51 is provided applied business.

Fig. 8 is the flow chart that the processing operation of applied business under the situation of message exchange 10 is used in expression.Message exchange 10 is arranged at the external interface place of applied business portion 20 in server computer 1.

In case the requirement from a certain terminal equipment is arranged, message exchange 10 promptly receives the information (step B11) of this terminal equipment from applied business portion 20.At that time, the terminal equipment of transmit leg is under the situation of the PC41 in the office, since irrelevant information switch 10 (step B12), the conventional treatment (step B13) of server computer 1 execution graph 7 explanations.

On the other hand, transmit leg is under the situation of portable terminal 31 outside the office or portable PC 51, enters message exchange 10 and carries out the program (step B12) that information exchanges are handled.

Message exchange 10 carries out information exchange (step B15, B16) from the terminal attributive information (step B14) that end message management department 12 obtains this terminal equipment according to the information that this terminal attributive information transmits application business department 20.So-called information exchange under this situation is exactly the disposal ability according to this terminal equipment, changes the form of a certain information, eliminates the terminal attribute influence.

When for example transmitting image information,, then this image information is transformed into symbolic information and transmits if the other side's terminal equipment does not have image-capable.By means of this,, also can accept the business identical with other-end equipment even change in the end side form.With such way, carry out information exchange corresponding to terminal attribute after, message exchange 10 just sends the information after this conversion to this terminal equipment (step B17) as business information.

Here to the reading of terminal attribute from terminal attribute management department 12 be illustrated.

Comprise in the terminal attribute picture dimension for example, picture control information, can be on picture the kind etc. of data presented.

Terminal attribute read two kinds of methods:

(A) read from the terminal attribute table that is arranged in the end message management department 12, and

(B) obtain terminal attributive information from terminal equipment.

In this example, preceding a kind of method (A) is used in the situation that terminal equipment is a portable data assistance 31.Then a kind of method then is used in the situation that terminal equipment is a portable PC 51.(A) with (B) selection, be after user's Information Management Department 14 is obtained the corresponding relation of user's name, terminal address and the communications infrastructure from user's information table management department 142, manage by terminal attribute that execution portion 123 judges.Ability at the CPU of end side is abundant, and communication line is under the situation of high-quality circuit, adopts back a kind of method (B) of consulting with the end side terminal attribute.

As for method (B), the communication protocol of decision terminal attribute can determine between terminal and server (message exchange 10).The notion of communication protocol sequence is shown in Fig. 9.Shown in this communication protocol sequence, between terminal and server (message exchange 10), confirm the control routine system (line feed code, mark etc.) of end side and bit map, picture dimension, available font classification (comprising corresponding language) etc. mutually.

Method to information exchange is illustrated below.

Information exchange does not have display capabilities in terminal one side, and the message transmission capability deficiency of the communications infrastructure, must with server carry out the amount of information or matter aspect conversion etc. carry out under the situation.

Information exchange specifically has

From binary data be transformed to text data conversion,

From image information be transformed to symbolic information conversion,

From icon data be transformed to symbolic information conversion,

Be transformed to the conversion of black and white image etc. from coloured image.

Below wherein the conversion from the binary data to the text data is illustrated.With uses such as for example PC be used for the application software of documenting the time, when being word processor, the file data that makes is often preserved with binary data, and this is because not only will preserve text data, and will preserve various satellite informations such as file format and font.

But it is big that common this binary data and simple text data are compared data scale.And in order to show this binary data, end side not only needs the text display ability, also needs the display capabilities of various images.And, often the back demonstration need processed to the server side file data owing to the picture dimension of end side often designs for a short time for the ease of carrying.

In order to handle such problem, information exchange is effective.That is to say, binary data is transformed to text data is sent to terminal equipment.By means of this, just can be fit to the processing of the disposal ability of self in end side.

The processing operation of information exchange at this moment is shown in Figure 10.

Figure 10 is the flow chart of the processing operation of the information exchange that adapts with terminal attribute of expression.Lifting word processor as applied business is example, and message exchange 10 is the address of user's data information management portion 114 retrieving files data in server at first, understands this document data and which type of form to preserve (step C11) with.

As a result, if file data is binary data ("Yes" of step C12), then message exchange 10 carries out unit expansion, (step C13) in 113 pairs of these binary file data of information exchange execution portion by various element distribution such as text, form, fonts.Then, from the information (step C14, C15) of each key element unit retrieval, extraction necessity, be the information format (step C16) that is fit to the terminal picture with this information reprocessing.The information of reprocessing was just carried out the business information of the word processor of information exchange according to terminal, offer this terminal equipment by message exchange external communication interface portion 116.

Again, other information exchanges are also identical, for example when end side does not have image-capable, maybe this image section is transformed to symbolic information, or icon is transformed to symbolic information.And when end side does not have the acoustic processing ability, become text to transmit sound mapping, can provide and the corresponding business of various disposal abilities with this.

On network, exist following business information that provides as applied business of situation of various terminal equipments to transmit like this by the form that information exchange becomes the disposal ability that is fit to each terminal equipment, can make portable the raising, and can construct distributed network computing system with information processing capability (operational capability) and the picture demonstration/user interface providing capability terminal equipment (PDA etc.) poor than other-end equipment (PC etc.), even terminal equipment side changes form, also can accept the service identical with other-end.

Also have, such information exchange except the disposal ability of terminal equipment itself, also can be implemented according to the method for operation of each terminal equipment.

That is to say, when the user utilizes applied business, on terminal equipment or handle icon, or action button, or input instruction etc., its method of operation is different because of terminal equipment.The method of operation of so various terminal equipments is registered in user interface information management department 13 in advance as user interface information, each terminal equipment is carried out information exchange according to above-mentioned user interface information, the service that can often provide with the method for operation acceptance that each terminal equipment is fit to.

Again can be according to the user's who operates this terminal equipment hobby implementation information exchange.

That is to say that the user moves on to central observation when utilizing applied business on terminal equipment or with relation curve, or make text keep original position to observe, user's difference, the display position of liking is also different.This picture is shown that hobby (picture demonstration taste information) is registered in user's Information Management Department 14 in advance as user's information, each user carries out information exchange according to above-mentioned user's information, and the business that provides then can be provided on the relevant position that the user liked of being everlasting.

Below the situation of carrying out information exchange corresponding to the communications infrastructure is illustrated.

Message exchange 10 is grasped the information of the communications infrastructure that is using about terminal user by means of the user's information table management department in the communications infrastructure Features Management portion 152 in the communications infrastructure management department 15 and the user's Information Management Department 14 142.And according to the control of the retransmission process of these information implementation data.

The processing operation of information exchange at this moment is shown in Figure 11.

Figure 11 is the flow chart of the processing operation of expression and the matched information exchange of the communications infrastructure.Use for example user under the situation of portable PC 51, can judge the CPU ability height ("No" of step D11) of terminal equipment.At this moment, if the data transmission capabilities height of the communications infrastructure ("No" of step D16), then in the information exchange handling part 11 of message exchange 10, after compressing with 115 pairs of data of compression/cryptographic processing portion as required and encrypting, carry out data and transmit (step D17).And if the data transmission capabilities of the communications infrastructure low ("Yes" of step D16), then carry out for example binary data being transformed to text data, or format informations such as center adjustment are become blank character, or the information exchange of ignoring font information etc. handles, and changes to send data (step D18) after sending data scale.

On the other hand, irrelevant with the communications infrastructure under the situation of using the low portable data assistance 31 of CPU ability ("Yes" of step D11), carry out information exchange with illustrated the same of Figure 10 and handle (step D12～D15).

So at first see the disposal ability of terminal equipment,, carry out and the corresponding information exchange of this communication capacity if its ability height is then then seen the communication capacity of the communications infrastructure.On the other hand, under the low situation of the disposal ability of terminal equipment,,, can only carry out and the corresponding information exchange of the disposal ability of this terminal equipment because terminal equipment can't tackle no matter how high the communication capacity of the communications infrastructure is.

By means of this, even in the various communications infrastructures and the system that deposits, also can eliminate the relative difference of the communications infrastructure,, also can accept the business identical with other-end equipment even the end side form changes at message transmission rate/quantity/aspects such as quality.

Also have, above-mentioned information conversion method can be realized with the recording medium that records the program information of recording and narrating this processing method.

That is to say, the gimmick of in above-mentioned example, putting down in writing, as the program that computer is carried out, for example can write also that mediums such as disk (floppy disk, hard disk etc.), CD (CD-ROM, DVD etc.), semiconductor memory are used in various devices, or be used in various devices by means of the communication medium transmission.The computer (server computer 1) of realizing this device reads in the program that writes down on the recording medium, with this program control operation, implements above-mentioned processing.

The situation that data are encrypted is illustrated below.

Utilizing outside office under the situation of applied business, in order to ensure the secret of this applied business, is very important with the data encryption transmission.In this case, end side must have the ability of understanding enciphered data, therefore can not transmit enciphered data to all terminal equipments.Again, in a single day data encrypt, and data volume promptly increases, and therefore, the data transmission capabilities of the communications infrastructure also must improve.

Figure 12 represents processing operation at this moment.

Figure 12 is the flow chart of the processing operation of expression when carrying out data encryption.When applied business such as various application software are provided in applied business portion 20, message exchange 10 is at first obtained the attribute information (step e 11) of terminal equipment as the other side of communication from terminal equipment Information Management Department 12, judges the disposal ability (step e 12) of terminal equipment according to this attribute information.

Consequently, in case be judged as the disposal ability height, has the ability ("Yes" of step e 12) of understanding enciphered data, message exchange 10 is obtained the communications infrastructure information (step e 13) that this terminal equipment connects from communications infrastructure Information Management Department 15 with that, judges communication capacity (step e 14) according to this communications infrastructure information.And under the high situation of communication capacity ("Yes" of step e 14), message exchange 10 sends to terminal equipment (step e 16) with the business information of this encryption after 11 pairs of these applied business information encryptions of information exchange handling part (step e 15).By means of this, can after understanding enciphered data, utilize this business in end side.

On the other hand, low in the terminal equipment disposal ability, not understand under the situation of ability of enciphered data ("No" of step e 12), message exchange 10 is not to this applied business information encryption (step e 17) transmission (step e 16) of just remaining untouched.At this moment the user that also can deliver a letter informs and does not encrypt.Or under the situation of the ability of not understanding enciphered data ("No" of step e 12), also can before send data, require end side to judge whether transmission is suitable, and send processing according to its answer.

Again, at terminal equipment disposal ability is arranged, and under the low situation of the communication capacity of communication network that this terminal equipment connects ("No" of step e 14), message exchange 10 is not to this applied business information encryption (step e 17) transmission (step e 14 "No") of just remaining untouched.Perhaps under the low situation of the communication capacity of communication network (step e 14 "No") also can require end side to judge whether transmission is suitable, and send processing according to its answer before send data

Also have, when data encryption, have from only being that in addition scramble is to the encryption of the various levels of carrying out the height encryption, the burden of bringing for the terminal equipment and the communications infrastructure also has nothing in common with each other.Therefore, also can encrypt level corresponding to the disposal ability of terminal equipment and the communication capacity appropriate change of the communications infrastructure.

Grasp encryption function like this,, also can guarantee its confidentiality even applied business is accepted in the place beyond office.In this case, can which kind of can carry out according to the determined property of the terminal attribute and the communications infrastructure and encrypt, the employed communications infrastructure can transmit the enciphered data of how much quantity, carries out suitable encryption.

Below the situation of carrying out data compression is illustrated.

Data compression is effective portion when the big message transmission of data volumes such as view data.Also as above-mentioned data encryption, need the ability of the data of compression being carried out extension process in end side in this case.Also have,,, just can transmit the data of compression, therefore, the communication capacity of the communications infrastructure is not discussed here as long as take the time for the communications infrastructure.

Figure 13 represents processing operation at this moment.

Figure 13 is the flow chart of the processing operation of expression when carrying out data compression.When applied business portion 20 provides applied business, message exchange 10 is at first obtained the attribute information (step F 11) of terminal equipment as the other side of communication from end message management department 12, judges the disposal ability (step F 12) of terminal equipment according to this attribute information.

The result, in case distinguish its disposal ability height, the ability ("Yes" of step F 12) of understanding packed data is arranged, and message exchange 10 promptly compresses the business information that will compress back (step F 13) in 11 pairs of these applied business information of information exchange handling part and sends to terminal equipment (step F 14).Can after end side is with the packed data expansion, utilize this business with this.

On the other hand, low in the terminal equipment disposal ability, do not expand under the situation of ability of packed data ("No" of step F 12), message exchange 10 does not compress (step F 15) to this applied business information, intactly transmits (step F 14).At this moment, the user that also can deliver a letter informs and does not compress.

Give data compression function like this, can carry out transfer of data effectively.In this case, can judge that any data compression is possible according to terminal attribute, to carry out appropriate compression.

Also have, in the example of Figure 13, just according to the disposal ability judgment data compression of terminal equipment whether may, but also can take the communication capacity of the communication network that this terminal equipment connected into account, whether feasible with the judgment data compression.

Moreover, can also be corresponding to the level of the communication capacity appropriate change compression of the disposal ability of terminal equipment and the communications infrastructure.

Below then to utilize the situation of applied business to be illustrated with input-output equipment.

Here the input-output equipment of saying is meant the equipment beyond the computer, is portable phone 32, beep-pager 33, facsimile machine 34, printer 42, image reader 43 in the example of Fig. 1.

Figure 14 is expression utilizes the processing operation under the situation of applied business with input-output equipment a flow chart.Send the signal (step G11) that will utilize applied business in case receive the user, message exchange 10 carries out the kind (step G13) that (step G12) behind user's the authentification of user judges the equipment that this user uses by user's Information Management Department 14.

Here, if the user is using input-output equipment ("Yes" of step G13), message exchange 10 promptly carries out the information exchange (step G14) that adapts with this input-output equipment, and sends the business information (step G15) of this information exchange.

Specifically, if input-output equipment is portable phone 32, message exchange 10 just utilizes the acoustic processing function, and for example text data is transformed to voice data, provides professional as acoustic information.

Again, if beep-pager 33, the message data that then is transformed to the regulation number of words transmits, if facsimile machine 34 then can become text data view data and transmit.And so on, in the specific limited scope that adapts to each input-output equipment, provide professional.

On the other hand, if the user uses is not input-output equipment, but have the terminal equipment ("No" of step G13) of CPU disposal ability, then message exchange 10 is carried out conventional applied business (step G16).Promptly after the information exchange that each terminal equipment is carried out adapting with separately disposal ability, provide professional.

Carry out the information exchange that adapts with input-output equipment like this,, also can provide its corresponding business even for example use the user under the situation of facsimile machine etc.

Also have, also can take all factors into consideration the attribute of input-output equipment and the attribute of the communications infrastructure, the business information from server is carried out information exchange.

Figure 15 is the block diagram of structure of the distributed network computing system of expression the present invention the 2nd example.The part identical with Fig. 1 is marked with identical symbol, omits its explanation.

In Figure 15, be with Fig. 1 difference, there is multiple servers computer 1a～1e on the network.Here, server computer 1a～1e is interconnecting by wired lan 2 in office.

Wherein, server computer 1a provides professional master server computer, has applied business portion 20.In this server computer 1a, information exchange handling part 11 is installed, as the information exchange Control Server work of the processing of managing the full detail exchange.

Again, other server computers 1b～1e is the child servers computer.The end message management department 12 that is used for the office terminal attribute information is installed on the server computer 1b, under the control of server computer 1a, works as the end message management server.The user interface information management department 13 that is used for management of user's interface information is installed on server computer 1c, under the control of server computer 1a, works as the user interface information management server.User's Information Management Department 14 is installed on the server computer 1d, under the control of server computer 1a, works as user's information management server.Communications infrastructure Information Management Department 15 is installed on the server computer 1e, under the control of server computer 1a, works as communications infrastructure information management server.

On these server computers 1a～1e, connect various terminal equipments (portable data assistance 31, PC41, portable PC 51 etc.) by various communication networks (public network 30, wired lan 40, WLAN 50 etc.).

That is to say.In the 2nd example, end message management department 12, user interface information management department 13, user's Information Management Department 14, communications infrastructure Information Management Department 15 are installed in the different last formation of server computer 1b～1e distributed processing system(DPS)s, the server computer 1a of mount message exchange handling part 11 controls various processing, realizes unified as a whole information exchange processing capacity with this.

And, the Control on Communication that message exchange intercommunication interface 111 at this moment shown in Figure 2 is administered between each server, message exchange external communication interface portion 116 management applied business and with the Control on Communication of other various terminal equipments.

Again, in the example of Figure 15, make the needed various functions of information exchange disperse one by one to be loaded among each server 1b～1e, still, also the function more than 2 can be loaded into a server computer, or identical functions is loaded on the multiple servers computer.

Operation to the 2nd example is illustrated below.

Figure 16 is the flow chart that the distributed treatment of expression the 2nd example provides the operation of business.When certain terminal equipment provides applied business, server computer 1a at first understands the required function of information exchange (step H11).The needed function of information exchange is meant terminal attributive information and communications infrastructure management of information function in this case, is meant user interface information and user's management of information function again.

Here, for example carrying out corresponding to terminal attribute under the situation of information exchange, the management function that needs terminal attributive information, thereby server computer 1a visits other server computers 1b～1e respectively, the server computer (step H12) that investigation has this management function.At this moment owing to have the situation that makes a plurality of server computers have same function, server computer 1a that the server computer that meets is confirmed one by one, selection can be used the server computer (step H13, H14) of this function.

In the example of Figure 15, server computer 1b meets.In this case, have one of the just server computer 1b of the management function of terminal attributive information, therefore, server computer 1a and server computer 1b obtain communication, wait for the usage license from server computer 1b.

When the usage license ("Yes" of step H14) of server computer 1b has been arranged, server computer 1a obtains the terminal attributive information of terminal equipment as the other side of communication by means of the end message management department 12 that is had from server computer 1b, and the business of carrying out the sort of dependence information exchange of above-mentioned the 1st example explanation provides processing (step H15).

That is to say that server computer 1a will be transformed into particular form at information exchange handling part 11 as the business information that service provides according to above-mentioned terminal attributive information, and send business information after this conversion by the communication network that this terminal equipment connected.So-called information exchange under this situation is the form that changes certain information according to the disposal ability of terminal equipment as the other side of communication.

It more than is the example that carries out under the situation of the information exchange that adapts with terminal attribute, with top described identical, for example carrying out according to the communications infrastructure under the situation of information exchange, respectively each server computer 1b～1e is conducted interviews the server computer that investigation has communications infrastructure management function.The result, the communications infrastructure Information Management Department 15 that has from the server computer 1e that meets is obtained the communications infrastructure information as the other side's of communication terminal equipment, provides processing with this business of carrying out the sort of dependence information exchange of the 1st example explanation.So-called information exchange in this case is the form that changes a certain information according to the communication capacity of the communication network that terminal equipment connected as the other side of communication.

And carrying out according to the user interface attribute under the situation of information exchange, then visit each server computer 1a～1e respectively, the server computer that investigation has the user interface information management function.Consequently, obtain and the other side's the corresponding user interface information of terminal equipment from the user interface information management department 13 that the server computer 1c that meets is had, provide processing with this business of carrying out the sort of dependence information exchange of above-mentioned the 1st example explanation as communication.So-called information exchange in this case is the form that changes certain information according to the method for operation (with reception applied business such as icon, button, instructions time method of operation) as the other side's of communication terminal equipment.

Again, when the attribute according to the user carries out information exchange, each server computer 1b～1e is conducted interviews, investigation has the server computer of user's information management function.Consequently, the user's Information Management Department 14 that has from the server computer 1d that meets is obtained and as the corresponding user's information of terminal equipment to the other side of letter, provides processing with the service of the sort of dependence information exchange of carrying out above-mentioned the 1st example explanation.So-called information exchange in this case is according to using user's method of operation as the other side's of communication terminal equipment (method of operation of liking aspect users such as picture display message), changing the form of certain information.

Like this, even various functions are disperseed, also can obtain identical effect with above-mentioned the 1st embodiment as message exchange, also have, various functions are disperseed, made up, can realize the information exchange processing capacity of height with this multiple servers that disposal ability is not high comparatively speaking.In this case, the processing that alleviates the server (the server computer 1a of Figure 15 a) that provides professional with distributed treatment is born, therefore, even minicom also can do with.Because a plurality of server capable of being combined is realized exchange, compare with the system of concentrated again, the processing when in system obstacle being arranged is more flexible.

Also having, in above-mentioned the 2nd example, is the object divergent function with the multiple servers on the public wired lan 2 that is connected in the office, but can be the object divergent function with the multiple servers that is connected on the various communication networks such as public network 30 for example also.

Again, when searching server, in above-mentioned the 2nd example, interknit with each server respectively, but the invention is not restricted to this with desirable function.For example also can keep the table of what kind of function with reference to each server of expression, seek suitable servers.Can also will be scattered in other servers with the function of carrying out data compression for the function of data encryption.In this case, if data encryption could be encrypted data according to terminal attributive information and communications infrastructure information at the server with this function with regard to judging, when data encryption is possible, the business information that provides as applied business is encrypted.The server of carrying out applied business receives the business information of this encryption, and it is sent to terminal equipment as the other side who communicates by letter.

Equally, if data are compressed, then judge and to carry out data compression according to terminal attributive information and communications infrastructure information having on the server of this function, in the time can carrying out data compression, will be compressed as the business information that applied business provides.The server of carrying out applied business receives the business information of this compression, sends it to the terminal equipment as the other side of communication.

Below the present invention's the 3rd example is illustrated.

The 3rd example is illustrated the situation that realizes message exchange on switch.

Figure 17 is the block diagram of structure of the comprehensive server 60 under the situation that realizes message exchange on the switch of expression the 3rd example.The device that this circuit switching exchange and server computer are integrated is called comprehensive server here.

As shown in figure 17, configuration information switch 61 on this comprehensive server 60.Message exchange 61 is the devices that carry out information exchange according to the attribute of the terminal equipment and the communications infrastructure, and concrete structure is identical with the message exchange 10 of Fig. 1, therefore omits its explanation here.

On comprehensive server 60, be provided as the office system applied business 62a of portion of server computer again.The 62a of applied business portion carries out the various applied business (application software) of office systems such as inventory management business.Existing situation is that owing to this not change of 62a of applied business portion just directly can not be loaded on the real time operating system (calling real-time OS in the following text) 67, empty computer 64 is got involved in the centre.0S67 handles applied operating system in real time in real time, and is different with general operating system (for example UNIX and MS-DOS), is to pay attention to response speed.

Also have, if the office system applied business 62b of portion that can start on real-time 0S67, the centre stays out of empty computer 64 and just can directly be loaded on the real-time OS67.Empty computer 64 be virtual foundation computer, identical with an actual computer on function, can on the empty computer of a cover, make an operating system.In this example, empty computer 64 is included circuit switching exchange 63 in.

Circuit switching exchange 63 is made of empty computer 64, real time system application business department 65, switch function portion 66.The business of reception (on duty), message switching regular phone systems such as (beep-pagers) is acted on behalf of by real time system application business department 65.Switch function portion 66 has the function of machine in return such as circuit connection and telephone number management.Figure 18 represents its structure.

As shown in figure 18, function of exchange portion 66 is made of terminal control part 71, professional control part 72, operation maintenance portion 73.Terminal control part 71 carries out sending it to controls such as next place such as the next signal of receiving terminal apparatus.Professional control part 72 judges to carry out what kind of business according to signal.Operation maintenance portion 73 here also comprises telephone number information etc. is provided except the circuit error message is provided.

Again, hardware 68 is represented for example entity such as CPU, circuit circuit part.

By means of such structure, can realize having both the online circuit switching exchange that exists of telephone communication and the device of message exchange.In this case, use this comprehensive server to carry out information exchange, be transformed into final form in place near user's terminal equipment.That is, when constructing network, can carry out information exchange, be transformed into the form that is fit to this sub-network by various sub-networks.

Again, comprehensive server storage data in terminal, thereby this comprehensive server utilizes as cache (cache) the most at last, only sends data of simplifying to the terminal equipment notice as the other side of communication, just in the meaning of cache memories stores data.By means of this, the loss of data volume is reduced to bottom line, and can replenishes the characteristic of each sub-network.

And, if be furnished with function of exchange, also can be used as office server.In this case, often dispose a plurality of switches on network, therefore, such distributed treatment of above-mentioned the 2nd example explanation becomes effective.

Also have, in the example of Figure 17, the message exchange of in server computer, switch comprehensive server in aggregates, packing into, but the invention is not restricted to this, for example also message exchange can be independent of comprehensive server (server computer+switch) and be provided with, the form that the applied business that comprehensive server is provided at message exchange is transformed into regulation transmits.The various functions of message exchange can be disperseed to be arranged at many switches again.To sum up, the present invention can do various changes in the scope that does not break away from its main idea and implemented.

Situation to configuration information switch on switch is illustrated below.

Figure 19 is the block diagram of structure of the scatternet computer system of expression the 3rd example.Take in office 81 structure that PC82, PC83 is set and is connected in the comprehensive server 85 of PC82, PC83 by wired lan 84 now.Comprehensive server 85 is that server computer and PBX (private branch exchange) are made holistic computer, can be used as switch work, provides applied business as server computer again simultaneously.On the other hand, the structure of taking that again PC92 is set and be connected in the comprehensive server 94 of PC92 by wired lan 84 in office 91.Comprehensive server 94 is the same with comprehensive server 85, is server computer and PBX (private branch exchange) are made holistic computer.

Again, the 100th, public network, the 101st, be present in the local exchange machine on the public network.And 102 are portable terminals that the business provide is provided.This portable terminal 102 is connected with comprehensive server 94 with internal radio 95 in office 91.

In such structure, the applied business that comprehensive server 85 in the office 81 provides can be gone up at the terminal equipment in being arranged at same office (PC82, PC83) and utilize, and also can utilize on the terminal equipment in being arranged at other offices 91 (PC92, portable terminal 102).

Here, being provided with on the PBX85a of server 85 under the situation of message exchange function, shown in Figure 20 A, the business information that comprehensive server 85 provides is delivered to comprehensive server 94 by PBX85a, public network 100.If at this moment the user uses portable terminal 102, then can receive the business information that provides from comprehensive server 94 by internal radio 95.But, owing to reasons such as amount of information is too much can not receive with portable terminal 102 under the situation of this business information, retransmit this business information after must carrying out information exchange at the PBX85a of comprehensive server 85.

On the other hand, also information exchange functions can be disperseed to be arranged at the PBX85a of comprehensive server 85 and the PBX94a of comprehensive server 94.At this moment shown in Figure 20 B, PBX85a can only judge what kind of terminal equipment the user uses, and business information is delivered to the comprehensive server 94 of terminal with the form that maintains the original state.At this moment server info is delivered to comprehensive server 94 by PBX85a, public network 100.Judge the communications infrastructure of the terminal equipment that the user uses with the PBX94a of comprehensive server 94, this business information is carried out transmitting after the information exchange according to the data transmission capabilities of this communications infrastructure.

At this moment, amount of information in this business information is many, and the user uses under the situation of portable terminal 102, if only send the notice that provides professional to portable terminal 102, and will be loaded on the PC92 under this business information with original form, even then do not retransmit business information separately from comprehensive server 85, the user directly removes to observe PC92, or portable terminal 102 is connected in wired lan 93, the also business that can accept to provide.That is to say, can use the comprehensive server of the terminal that terminal equipment connected of the business of accepting to provide as cache, consequently, can save time, also save the expense of using circuit simultaneously.

Make circuit switching exchange have information exchange functions like this, can carry out information exchange, be transformed into final form in place near user's terminal equipment.In a word, when constituting network, can carry out information exchange, be transformed to the form that is fit to this sub-network by each sub-network.

Also have, above-mentioned the 3rd example is that object is illustrated with the circuit switching exchange, but the invention is not restricted to this, for example also can be the router that LAN is connected to each other usefulness.To sum up, so long as network (being public network on circuit switching exchange, is LAN on router) is connected to each other the network connection device of usefulness, the mount message switch just can obtain and top described same effect on this network connection device.

Again, in above-mentioned each example, the terminal equipment of the applied business that acceptance is provided also can be the equipment as server computer work.

Also have, the method of putting down in writing in above-mentioned example also can be used as the program that computer is carried out, or for example write that recording mediums such as disk (floppy disk, hard disk etc.), CD (CD-ROM, DVD etc.), semiconductor memory are used for various devices, or transmit with communication medium and to be used for various devices.The computer (server computer 1) of realizing this device reads in the program that writes down on the recording medium, with the program control action, thereby carries out above-mentioned processing.

Below the present invention's the 4th example is illustrated.

Figure 21 is the concept map of structure that expression comprises the whole system of the applied business under the situation of imagining structured document.161 is structured document management departments among the figure, the business information that provides as the applied business of various application software etc. with the structured document format management.This structured document management department 161 is arranged at the applied business portion of Fig. 1.Also have, the situation of the business information that 20 management of applied business portion are recorded and narrated with the structured document form in advance is described, but as following described, this business information also can not be a structured document form (with reference to Figure 26) here.

The 162nd, information exchange portion carries out information exchange according to the attribute of the terminal attribute and the communications infrastructure.This information exchange portion 162 is equivalent to the message exchange 10 of Fig. 1.The 163rd, Network Dept., the various communication networks of expression association service device and terminal.This Network Dept. 163 is equivalent to public network 30, wired lan 40, the WLAN 50 of Fig. 1.164a～164c is the terminal equipment that the business provide is provided from server, for example PC (personal computer), NC (network computer), PDA (PDA (Personal Digital Assistant)).These terminal equipments 164a～164c communications infrastructure has nothing in common with each other, and disposal ability is also different.In Fig. 1, be equivalent to portable data assistance 31, PC41, portable PC 51.

In such structure, the applied business of various application software etc. manages with structured document form (for example html file) in structured document management department 161.Here, Figure 22 represents an example of structured document.

In Figure 22, mark 171 expressions are sentenced the situation that the back text data arrives from this.Again, mark 172 expression file format information are adjusted (" centering ") to the center here and are given a definition.Mark 173 expression font informations define the big font of model here.Mark 174 expression font informations.

Information exchange portion 162 resolves this structured document, according to the kind and the data scale thereof of each unit that inserts the label information investigation formation this document in this document.Then, when sending each cell data, understand the communication capacity of terminal equipment and the communication capacity of the communications infrastructure, carry out and the corresponding information exchange of this ability.

For example, under the low situation of the data transmission capabilities that is judged as the communications infrastructure, the file that data volume is many is sought to cut down the transmission data with information exchange (or data compression).When judging that according to terminal attribute terminal equipment as the other side of communication does not have the file display capabilities (situation that does not have the terminal of loading browser), carry out information exchange again, become the laggard line data of form that end side can show and send.

Also when carrying out information exchange, carry out data change according to user's hobby and make its appearance consistent (is the information exchange processing of foundation with user's information) with the file demonstration.

The following describes concrete processing operation.

Here to describing, and will be narrated below with Figure 26 about situation with the business information of applied business portion 20 management unstructured document forms with the operation under the situation of the business information of applied business portion 20 managing structured document forms.

At first the processing corresponding to terminal attribute is illustrated.

Figure 23 is that the flow chart corresponding to the processing operation of terminal attribute is used under the situation of structured document in expression.In Fig. 1, the applied business portion 20 in the server computer 1 is managing the business information of recording and narrating with the structured document form.In case a certain terminal equipment has documentation requirements indication (business need indication) to server computer 1, promptly deliver to message exchange 10 from applied business portion 20 with the business information that the structured document form is recorded and narrated.Message exchange 10 is carried out as following information exchange described by means of this and is handled.

That is message exchange 10 is at first resolved (step H11) to the structured document that constitutes this business information.In this case, in structured document, be that the grammer that representative is stipulated gives a definition for each unit in order to label information, thereby message exchange 10 limits are investigated the kind and the data scale (step H12) thereof of each unit that constitutes this document according to this label information.Here it is for example investigates how many image informations has, and where is present in, and how many programs has, and where is present in.

And information exchange is hereinafter described added in such unit resolves, retrieval, extraction of resolving by means of file, and the information exchange execution portion 113 (Fig. 2) of this a series of processing in information exchange handling part 11 carries out.

After structured document was resolved, message exchange 10 was obtained attribute information as the other side's of communication terminal equipment from end message management department 12, investigates its disposal ability (step H13).As a result, the disposal ability that is judged as end side is low, and when not having the ability of structured file, message exchange 10 is transformed to the form (step H14) that this terminal can show to each cell data of this structured document.

That is to say, under the low situation of the image control ability of terminal equipment (terminal that does not have browser function), for example the information that provides as business information is image information, particularly during animation information, it is become symbolic information (information that simply shows this image with certain form) transmit.And under the situation of format information that is file, it is become blank character or the transmission of dividing a word with a hyphen at the end of a line, under the situation of character type, because terminal can not be handled and be ignored.Also have, the program that " Java " and " Active " worked in client computer (terminal) side like that can not be handled and ignores owing to terminal, at this moment sends the notice that shows that program can not be handled.

Like this, when carrying out information exchange that the disposal ability with terminal equipment adapts, the business information that message exchange 10 will pass through information exchange sends (step H15) by the communication network that terminal equipment connected.By means of this, for example,, also can receive the business information that provide with the form that terminal has even when use does not have the terminal equipment of ability of structured file.

Below the processing corresponding to the attribute of the communications infrastructure is illustrated.

According to the information exchange that the attribute of the communications infrastructure carries out, the scale of having only each cell data is important.

Figure 24 is that under the situation of structured document and flow chart communications infrastructure attribute corresponding process operations are used in expression.In Fig. 1, the applied business portion 20 in server computer 1 is managing the business information of recording and narrating with the structured document form.In case there is certain terminal equipment that server computer is sent documentation requirements indication (business need indication), the business information of recording and narrating with the structured document form promptly is sent to message exchange 10 from applied business portion 20, thereby message exchange 10 is carried out information exchange processing as described below.

That is to say that message exchange 10 is at first resolved (step I11) to the structured document that constitutes this business information.In this case, in structured document, be that the grammer that representative is stipulated gives a definition for each unit in order to label information, thereby message exchange 10 is investigated the kind and the data scale (step I12) thereof of each unit that constitutes this document according to this label information.Here it is for example investigates how many image informations has, and where is present in, and how many programs has, and where is present in.

And information exchange described below is added in such unit resolves, retrieval, extraction of carrying out by means of document analysis, and the information exchange execution portion 113 (Fig. 2) of this a series of processing in information exchange handling part 11 carries out.

After structured document was resolved, message exchange 10 was obtained attribute information as the other side's of communication the communications infrastructure that terminal equipment connected from communications infrastructure Information Management Department 15, investigates its communication capacity (step I13).As a result, under the low situation of the data transmission capabilities that is judged as infrastructure, message exchange is transformed to the form consistent with the data transmission capabilities of this communications infrastructure (step H14) to each cell data of this structured document.

That is to say, under the situation of the low communications infrastructure of data transmission capabilities such as for example PHS (Personal Handyphone System) data communication network, for example the information that provides as business information is image information, particularly during animation information, take methods such as its frame losings, transmit in the mode of cutting down amount of information.

Like this, when carrying out information exchange that the data transmission capabilities with the communications infrastructure adapts, the business information that message exchange 10 will pass through information exchange sends (step I15) by the communication network that terminal equipment connected.By means of this,, also can receive the business information that provides with the form that this communications infrastructure has even use for example low communications infrastructure of data transmission capabilities.

Below to being illustrated with terminal attribute and corresponding processing of communications infrastructure attribute.

Figure 25 is the flow chart that the processing operation that adapts with terminal attribute and communications infrastructure attribute under the situation of structured document is used in expression.In Fig. 1, the applied business portion 20 in the server computer 1 is managing the business information of recording and narrating with the structured document form.In case the documentation requirements indication (business need indication) of certain terminal equipment to server computer 1 arranged, the business information of recording and narrating with the structured document form and pass to message exchange 10 from applied business portion 20, thus message exchange 10 is carried out information exchange as described below and is handled.

That is to say that message exchange 10 is at first resolved (step J11) to the structured document that constitutes this business information.

In this case, in structured document, be that the grammer that representative is stipulated gives a definition for each unit in order to label information, thereby message exchange 10 is investigated the kind and the data scale (step J12) thereof of each unit that constitutes this document according to this label information.Here it is for example investigates how many image informations has, and where is present in, and how many programs has, and where is present in.

And such unit resolves, retrieval, extraction of carrying out by means of document analysis adds information exchange described below, and the information exchange execution portion 113 (Fig. 2) of this a series of processing in information exchange handling part 11 carries out.

After structured document was resolved, message exchange 10 was obtained attribute information as the other side's of communication terminal equipment from end message management department 12, investigates its disposal ability (step J13).The result, low in the disposal ability that is judged as end side, when not having the ability of structured file ("Yes" of step J14), message exchange 10 is transformed to (step J14) after the form that this terminal can show to each cell data of this structured document, sends business information (step J16) after this information exchange by the communication network that this terminal equipment connected.

On the other hand, be judged as the disposal ability height of end side, when having the ability of structured file ("No" of step J14), then message exchange 10 is obtained the attribute information (step J17) of the communications infrastructure that is connected as the distant terminal equipment of communicating by letter from communications infrastructure Information Management Department 15.Message exchange 10 carries out and the corresponding information exchange of the communication capacity of the communications infrastructure (step J18) according to this attribute information then, sends business information (step J16) after this information exchange by the communication network that terminal equipment connected.

Even provide like this under the situation of the business information of recording and narrating with the structured document form, by means of carrying out information exchange, can provide the service of the communication capacity of the disposal ability that is fit to terminal equipment and the communications infrastructure according to terminal attribute and communications infrastructure attribute.

And be not only such terminal attribute and communications infrastructure attribute, also can be by means of using for example user interface information management department 13 of Fig. 1, user interface information according to the intrinsic method of operation of each terminal equipment of expression carries out information exchange, or, carry out information exchange according to user's information of the intrinsic method of operation of each user of expression by means of user's Information Management Department 14.

Also have, carrying out data encryption, or data compression, or use under the situation of input-output equipment such as facsimile machine, be fit to the operations such as information exchange of this input-output equipment, when the business information of recording and narrating with the structured document form is provided, can using all methods recited above.

Again, in above-mentioned example, in advance the situation that the business information of recording and narrating with the structured document form is provided is illustrated, but the invention is not restricted to this, even the business information so that the form (binary data) different with the structured document form recorded and narrated also can make in this way.At this moment processing operation is shown in Figure 26.

Figure 26 is that expression is the flow chart of the processing operation under the situation of object with the business information beyond the structured document form.Here, the situation of carrying out information exchange according to terminal attribute is illustrated, and according to communications infrastructure attribute attribute, it is also identical to also have user interface information, user's information etc. to carry out the situation of information exchange.

Be to increase the structured document conversion process shown in step K 11, the K12 with the difference of the processing of above-mentioned Figure 23.This is that the information conversion that is used for for example binary form is the processing of structured document forms such as HTML.This structured document conversion process also information exchange execution portion 113 (Fig. 2) in information conversion handling part 11 is carried out.In this case, the applied business portion 20 in the server computer 1 is managing the business information of recording and narrating with the unstructured document form, and message exchange 10 is transformed to the structured document form with it.

In case the documentation requirements indication (business need indication) of certain terminal equipment to server computer 1 arranged, be about to be sent to message exchange 10 from applied business portion, thereby message exchange 10 is carried out information exchange processing as described below with the business information that the form that is different from the structured document form is recorded and narrated.

It is the cell data (step K 11) that message exchange 10 at first cuts out this business information of formation.At this moment, for example under the situation of the fileinfo of binary data, with token (token) management text, font, form and other attributes (date, author's name etc.).Thereby the investigation token just can cut out each cell data.In case cut each cell data, message exchange 10 is promptly made the structured document (step K 12) of expressing these unit with structured languages such as HTML.

After making structured document like this, be such processing that object carries out Figure 23 explanation with this structured document.

Just 10 pairs of these structured documents of message exchange are resolved (step K 13), and investigation constitutes the kind and the data scale (step K 14) thereof of each unit of this document.Message exchange 10 is obtained the attribute information (step K 15) of terminal equipment as the other side of communication from end message management department 12 then, according to this attribute information each cell data is carried out information exchange (step K 16).Message exchange 10 sends business information (step K 17) after this information exchange by the communication network that terminal equipment connected.

Like this, even under the situation of business information of recording and narrating with the unstructured document form,, also can access and top described identical effect by increasing the processing that this business information is transformed to the structured document form as object.

Above record in be example with structured documents such as HTML, but so long as for example OLE (objectlinking and embedding) wait file with each cell data formation, all can use.

Again, the method of being recorded and narrated in above-mentioned each example, as the program that can allow computer carry out, for example can write and be used for various devices on the recording mediums such as disk (floppy disk, hard disk etc.), CD (CD-ROM, DVD etc.), semiconductor memory, also can transmit and be used for various devices by means of communication medium.The computer (server computer 1) of realizing this device reads in the program that writes down on the recording medium, and by this program control operation, carries out above-mentioned processing.
